Answer:
x = -11/5 and y = 24/5
Step-by-step explanation:
Use elimination.
First, we need to multiply so that at least one variable can cancel out.
We can multiply the top equation by 2.
So we get
4x + 6y = 20
Then, we can use elimination.
The x's cancel out.
So we get 5y = 24
Or y = 24/5
Then, we can plug in this y value back into the first equation to find x.
2x + 3(24/5) = 10
2x + 72/5 = 50/5
2x = -22/5
x = -11/5
So x = -11/5 and y = 24/5
Answer:
Step-by-step explanation:
The truck is 315 inches long
The volume of this prism is: 240 cm3.
Because, in order to find the volume you have to do: V = w h l = 4 x 15 x 4 = 240.
(V = volume, w = width, h = height, and l = length)

Value of x = 19
(8x - 20) = (5x + 37)
3x = 57
x = 19
